400G OSFP RHS/Flat Top to 400G QSFP-DD400G OSFP RHS/Flat Top to 400G QSFP-DD Passive DAC Cable (OSFPFL-400G-QDDPCxxx)
The 400G OSFP RHS/Flat Top to 400G QSFP-DD Passive DAC Cable (OSFPFL-400G-QDDPCxxx) is a passive twinax direct attach copper cable with OSFP to QSFP-DD, supporting 400Gbps links over a length of customized length. As a passive cable it draws essentially no power and adds no latency to the link. It is a cost effective, low latency interconnect for 400G Ethernet data center and cloud network environments, and complies with IEEE 802.3cd, OSFP MSA, QSFP-DD MSA, CMIS Rev4.0, SFF-8417.

Applications
The 400G OSFP RHS/Flat Top to 400G QSFP-DD Passive DAC Cable (OSFPFL-400G-QDDPCxxx) connects OSFP to QSFP-DD ports at 400Gbps in 400G Ethernet data center and cloud network environments. It installs directly into standard ports with no separate transceivers or patch cords to manage at either end. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment. The link runs OSFP-4x100G PAM4 QDD-4x100G PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
This product is designed and tested to comply with IEEE 802.3cd, OSFP MSA, QSFP-DD MSA, CMIS Rev4.0, SFF-8417. It plugs into any standards-based OSFP to QSFP-DD port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
This model is supplied at standard length under part number OSFPFL-400G-QDDPCxxx. Other lengths of the same assembly can be produced on request. Volume pricing is available for project quantities.
Packing Details
Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.
Built to Your Spec
Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
Logistics
Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.
Quality and Testing
Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.
